Dale Figaro

I am looking for two siblings of mine. I recently found out the name of my fathers daughter. Her name is Lavonne Figaro I believe she was born around 1972. Her fathers name was Dale Figaro and her mothers name was Lou Seidle. I also believe she was born in los Angeles or Long Beach California. If any one knows any information please contact me. I also have a brother who was born in 1962 or 1963 who was given up for adoption. I have no name on him. I know he was born in Los Angeles California. His fathers name was Dale Figaro. Please contact me. Tracy Davis
